I am not sure what is your use case, but as far as we know, in some situation TS is unsafe, for example: the transform usage & Range etc.
we are using the following codes in the production, which don't crash that much. we do not use any plugin. https://gitorious.org/trafficserver/taobao/commits/3.2 please try it if you just want a working cluster :D we will make more codes into git/master if we are ready, some of the performance patches is not in the official tree right now.
